SPECIFICATION forming part of Letters Patent No. 401,508, dated April 16, 1889.

Application filed ,ray 1s, 1887.

To all whom t may concern.-

Be it known that I, WILLIAM C. METZNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stove Gratos; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the saine, ref erence being had to the accompanying drawings, and to let-ters or iigures of reference marked thereon, which form a part of this specification.

My invention relates to stove-grates, and has reference particularly to what are known as basket-grates for cooking-stoves.

The object of the invention is to provide a basket-grate adapted to be adjusted as to size to tit stoves of different sizes.

In the accompanying drawings, Figure l is a plan of the grate having the end walls reA moved. Fig. 2 is a rear elevation. Fig. 3 is an end elevation. Figa is an end elevation having the end wall removed. Fig. 5 is a transverse vertical section in line af of Fig. l. Fig. 6 is a section in line -g/ jz/ of Fig. l. Fig. 7 is a detail of the lower ends of the plates forming the end walls.

The principal parts of the grate are the 'overlapping sections A and B and the end walls, D D. The section A forms the front and a portion of the bottom of the grate, and the lower half of the front and the bottom portion thereof are composed of transverse y ribs A2, the upper half of the front remaining a solid part, The section B is applied to either the lower or the upper face of the rear portion of the section A in such manner as to adapt it to be moved backward or `forward with reference to the section A, to increase or decrease the width of the grate, as will be hereinafter described. The end walls, l), may also loe madcadjustable as to dimensions,

`and they may be adapted to be shifted on the sections A and B to vary the Vlength of the fuelchamber- The sections A and B may have combined with them a section, forming a part of the bottom, capable of being shaken or of being dumped, or which embodies both the shaking Serial No. 238,307. (No model.)

and dumping features. The drawings show such a section having the latter construction, and such section is herein termed the dump.7

The extension-section B is shown applied to the bottom of the rear portion of the section A, and provided with ribs t), corresponding to the ribs A2 in the section A. Bolts B', passf ing between the ribs A2 and I), bind said sections B and A together, (see Figs. l and 7,) and said bolts maybe moved between said ribs to allow the section B to be moved backward and forward horizontally beneath the section A, said section B forming aportion of the bottom of the grate, and adapt said bottom to be changed in width. To give said section B greater strength and to levelthe rear of the grate, the rear margin of said section may be cast with a fiange, B2, rising behind the rear margin of the section A even with the upper surface of the latter. B3 are short legs projecting downwardly from the bottom of the section B. Upon these the rear portion of the grate is supported when in the stove.

Fig. 1 shows the ribs A2 cut away at the middle of the horizontal portion of section A, thus forming the central. opening, A and at one end of the section A the upper faces of all the ribs A2V and at the opposite end at least the rib next to the opening A are provided with concave recesses e2 to receive the journals of the dump, which I next describe.

C is a dump occupying the opening A and having its upper surface on a level with the horizontal part of the section A, and having ribs c to correspond with the ribs A2 and t).

C and C2 are horizontal journals extending outwardly from the ends of said dump, parallel with the sides of the sect-ion A and a little forward of the middle of said dump. Said journals lie in the recesses a2 of the section A, and upon them the dump C may be partially rotated. 'lhe rear portion of said dump extends over the section B, and since the journals C and C2 are `forward of the middle of said dump, the portion of the latter at the rearof said journals will have a preponderance of weight over the portion at the front of said journals, and will therefore lie upon the plate B, excepting when tilted forward to dump the ashesand cinders. The

IOO

outer end of the journal C is made to extend a little beyond the edge of the section A, and has the sides of such end cut away or otherwise shaped to receive a wrench or other tool by which to turn the dump in a forward direction and empty the material upon the grate into the ash-receptacle below, as has been done heretofore in other grates.

Upon the upper side of the outer end of the journal C stands a post, c', while upon the adjacent part of t-he section A stands a similar post, c2. These are to be engaged by the eyes c2 of a shaker, C2. (Shown in the drawings.) By moving said shaker to and fro horizontally the dump is reciprocated lengthwise, the post c2 forming a fulcrum for t-he movement of the shaker and the dump C being enough shorter than the opening A to allow the desired movement of the dump. This reciprocal movement of the dump I term the shaking, while I term the rotation of it the dumping. Both of these operations are old.

D D are the end walls, and they are composed of the plates D -D2, overlapping and held together by a bolt, D2, passing through a hole, d', in the plate D', and a horizontal slot, cl2, in the plate D2. That portion of the plate D2 which is opposite the part A2 is shaped to fit closely against the latter, while immediately beneath said part A3 said plate D2 extends forward between the outermost ribs, A2, and forms a hip, d2, which engages the lower edge of the part A3. From the corner of tlie plate D2, beneath said hip d3, a leg, D4, extends downwardly between the ribs A2 even with the lower ends of the legs B2on the plate B. The rear portion of the grate is thus supported upon the feet B2, while the front thereof is supported upon the feet D4. The lower edges of the plates D and D2 are preferably extended into the space between the ribs A2 and the pair of such plates standing over the journal C', provided with the oblong notches Z4 d5 to make room for said journal. The lower rear corner of each of said plates D rests upon the upper surface of the horizontal portion 0f the grate. As will be readily seen by the drawings, each plate D2 maybe moved backward or forward when the bolts D3 are loose. The end walls, D D, may thus be made to conform to the width of the bottom of the grate. To provide for the further ad just-ment of the size of said walls, the free edges thereof may have the parallel breaking-grooves d, as shown in Fig. 3, said grooves facilitating the breaking of such edges to reduce the size of the plates.

In order that the length of the grate may also be reduced, the outer ends of the partA3 and the rear edge of the section A are provided with transverse breaking-grooves a3,

arranged in line with the spaces between the ribs A2, while the front and rear edges of the plate B are provided with similar grooves, b2. By means of these grooves the outer ribs, A2 and b, may be broken away. Vhen this has been donc, the walls D are seated between the then remaining outermost pair of ribs. These grooves may be formed at one or both ends of the grate, and may be multiplied so that any desired number of ribs A2 may be broken away. Then the aforesaid breakin ggrooves are formed at the end at which the journal C is located, a corresponding numn ber of the adjacent ribs A2 must be provided with posts (f2, to the end that such apost may remain after the grate has been reduced. lVhen more than one such post remains after the grate has been fitted to the stove, all except the outermost may be broken off.

In order that the journal C may be correspondingly shortened, it is provided with suitably-spaced breaking-grooves, c4, and additional posts, c, all except the outer of said posts remaining after the grate has been fitted to the stove -being broken away. These breaking-grooves are not in themselves new.

rllhe section A and dump C may be used without the section B when the section A is wide enough to lill the space in the fire-cham ber of the stove, and end plates different from the one shown herein used therewith. In such a case a web corresponding to the middle portion of section lB is to be extended across the opening A', beneath the rear end of the dump C, to support the latter. As such web is to occupy the position of the middle portion 0f said section B, and may be of the same form, I deem it unnecessary to illustrate the same separately in the drawings; and a section, A, having no dump, but having fixed ribs over its entire bottom, maybe used in combination with the end Walls, D, set between the outer pairs of ribs, A2, and forming a support for the front 'of the section A. In each of these cases the breaking-grooves may be provided to facilitate the reduction of the length of the grate.

I claim as my invention 1. In a stove-grate, the combination,with a section having an upright part to form the front of the iire-pot and a horizontal part to form the bottom thereof, of a horizontally-adjustable section overlapping the first-named section and end walls composed of adjustable overlapping plates set between the ribs of said sections, substantially as shown and described.

2. In a stove-grate, the combination, with a section having an upright part to form the front of the lire-pot and a horizontal part to form the bottom thereof, of a horizontally-ad j ustable section overlapping the first-named section and end walls composed of adjustable overlapping plates set between the ribs of said sections, said second section having legs to support the rear of the grate and the front plates of said end walls being each provided with a supporting-leg and ahip or its equivalent, by which it engages said first-named section and supports the latter, all substantially as shown and described.

3. In a stove-grate, a section, A, having an opening, A and recesses a2 in the ribs A2 at IOO IIO

each end of said opening A', a dump, C,lying in said opening and having its journals resting in the recesses a2, the ends of the section A being provided with breaking-grooves t0 facilitate the breaking away of the outermost ribs, A2, substantially as shown and described.

l. In a stove-grate, the con1bination,with a section, A, having` the transverse ribs A2, of end walls, I), having a hip and leg at -the front side and seated between said ribs and supporting the front of the section A, While the i'eai ot" said section is provided with supports, as legs B3, independent of said end walls, substantially as shown and described.

In a stove-grate, the combination, with a section, A, having` the transverse ribs A2, of end walls, D, having a hip and leg at the front side and seated between said ribs and supporting the front of the section A, while the rear of said section has applied to its lower side a section, B, from which depend legs whei'eon the rear of the grate is supported, substantially as shown and described.

In testimony whereof I afix my signature in presence of two witnesses. l
